From the experimental results, this paper analyzes the relations among the pipe-flow characteristics, solid characteristics, slurry characteristics and transporting method which affected resistance loss in two-phase flow, and does sensitive analysis by using standard regression coefficient method on important factors such as diameter of pipe, specific gravity, concentration and inclined angle to find the degree which have influenced.

根据实验结果，分析了管流特性、物料特性、浆体特性和输送方式对于两相管流阻力损失的影响关系，并首次采用多因素分析法对重要因素，如管径、比重、浓度、倾角等进行了敏感性分析，找出了其影响程度的大小关系。

A second set of toroids was made later, which employed a 21cm diameter plywood disk as their center, and two tubes as the actual toroid.

The round tube billet of sizing mill pushed two set of Turks-heads to form sharp corner in longitudinal direction.

在钢管纵向，利用定径机组的圆形管坯直接推进两架被动的土耳其头而形成尖角管。

We conclude that (1) S100A1 is a specific and sensitive immunohistochemical marker to differentiate nephrogenic adenoma from prostatic adenocarcinoma;(2) AMACR immunostaining does not seem to be a useful marker in distinguishing between these 2 lesions;(3) given that both S100A1 and AMACR have been reported to be expressed in renal tubular cells and in a subset of renal cell neoplasms, our findings confirm the histogenetic relationship between nephrogenic adenoma and renal tubular epithelium.

我们总结认为：（1）鉴别肾源性腺瘤和前列腺腺癌，S100A1既特异又敏感；（2）AMACR免疫染色鉴别这两种病变，效用不佳；（3）文献报道S100A1和AMACR均表达于肾小管上皮和部分肾细胞肿瘤，在此前提下，我们的结果证实了肾源性腺瘤和肾小管上皮之间的组织发生关系。
